Casey shot cell phone video of the State Police bomb squad clearing the bus. Her mom Irene was a nervous wreck at home in Bridgewater listening to it all play out over her police scanners.

“My husband was here keeping me as calm as I could and I wanted to stay calm so when I talked to Casey I could keep her calm,” Irene said.

State Police say they searched the bus and did not find anything and determined a student on board made the false threat.

“I think it’s pretty stupid to be honest with you,” Casey said. “I mean that’s not really a smart thing to do you can get in a lot of trouble and scare other people especially with what’s been going on recently.”

The students were eventually allowed to get their backpacks and went on a separate bus home. The student accused of calling in the bomb threat was arrested and will be charged.
